Description

Mixed ring type crossed blending system

Technical Field

The utility model relates to a weaving equipment technical field, more specifically say, relate to a mixed ring type's alternately blending system.

Background

Along with the continuous improvement of high-grade requirements of people on environmental protection, comfort, beauty and the like of clothes, the multi-variety fiber blending is exuberant and tends to be great. However, the existing blending process and technology still have many defects and bottlenecks, mainly:

1. and (4) strip mixing. After the fibers of each variety are subjected to scutching and carding processes to be carded, the fibers are subjected to drawing according to the calculated ratio of the number of the fibers (such as 3 fibers +5 fibers) on a drawing frame, and then are subjected to bonding and stretching to be mixed by cotton bundles. The drawing and mixing mode is adopted, and some of the drawing and mixing modes even reach three times, are complicated and cannot achieve the effect of uniform mixing, so that the condition that small white spots always appear on finished yarns is inevitable.

2. And (4) manual weighing. The method is characterized in that the cotton is manually distributed according to a proportion, the cotton is grabbed by a grabbing machine and then enters a packing machine, the cotton is grabbed by the grabbing machine again after the packing is finished, and the cotton cleaning → cotton mixing → cotton opening → cotton carding process flows are carried out. The disadvantages are that: packing after opening and then opening again, which inevitably causes fiber damage; the flow is tedious and labor-consuming, the personnel can easily generate error actions under long-time fatigue, the uniformity and the error rate are difficult to control artificially, and potential safety hazards exist in the production process.

3. A pound scale type. Namely, the electronic scale boxes are respectively arranged at the bottom of the cotton collecting box, and the electronic scale boxes are interlocked to carry out weighing proportion regulation. However, with frequent start and stop of the electronic pound box, the weighing sensor is arranged below a beater of the cotton collecting box and is inevitably influenced by vibration of a machine table, air flow, shaking of an air valve and cotton hanging, so that the weighing capacity of the electronic pound box fluctuates, the respective error value increases the whole error value, and simultaneously, the respective cotton is held and loosened after being overlapped in the conveying process to form a pile of mutually overlapped mixture, and the uniformity of the cotton cannot be ensured at all.

4. A tray type. The conveyer belt from the big cotton box to the horizontal opener is provided with a tray scale, the tray is a fixed flat plate, the weighing sensor is fixed and supported, the weight of the cotton layer can be measured by the cotton passing through the tray, and the conveying speed is changed according to the change of the thickness of the cotton layer so as to adjust and control the mixing ratio. However, the tray scale is only a plane supporting plate, the weighing is accurate when the same variety is processed, however, under the condition that the varieties are diversified in a small amount, due to the fact that the ends are changed, the front conveying belt pushes forwards, the rear conveying belt pulls backwards, the cotton varieties are different in nature, the drafting indexes are different, particularly after the varieties are changed, the measured weight is different inevitably, a section of proportion error is generated at any time, the accurate weight cannot be obtained immediately, and therefore the mixing effect of the varieties and the varieties in a small amount is difficult to control and improve.

Accordingly, there is a need to provide a new blending system that overcomes the above-mentioned deficiencies in the prior art.
